ultrasound questions....please someone help....

On my ultrasound i got it says two different things and i would just like someone to tell me what they mean. Ok the first thing says "CRL 26.6 and right under it it says GA 9w 4d." Can someone please explain to me what this means!!!!

Good news! I just had an ultrasound today (my first for this pregnancy) and my doctor told me GA means gestational age so if your ga is 9w 4 d that means the ultrasound puts your pregnancy at 9 weeks 4 days. One thing to note though is that the first ultrasound is the best predictor of how far along you are (i heard this with my first pregnancy in some book). So if this is your second ultrasound then the GA may not be very accurate, oh and my doctor said those ultrasound GA's are always a few days off. I hope this helps!
